SPECIFICATION forming part of Letters Patent No. 228,409, dated June 1,1880,

' Application tiled January 23, 1880.

To all whom it may concern:

Be it known that I, J osEPH M. SPRINGER, of Logansport, in the county ofCass and State of Indiana, have invented certain new and usefulImprovements in Flour-Bolts; and I do hereby declare the following to bea full, clear, and exact description of the invention, such as willenable others skilled in the art to which it pertains to make and useit, reference' being had to the aceompanyin g drawings, which form partot' this specification.

My invention relates to an improvement in bolting-reels; and it consistsin making a portion of the -arms which' support the boltingcloth movablein the central shaft at their inner ends, and connecting to thesemovable arms suitable springs for keeping them pressed constantlyoutward against the cloth, and rings for depressing and holding thesprings, whereby the cloth is kept automatically stretched to the properdegree or slaokened at will, as will be more fully described herein.

after.

Figure l is a longitudinal section of my i11- ven tion. Figxz is acrosssection of the same.

a represents the shaft, c the ribs, and d the bolting-cloth, all ofwhich are constructed in the usual manner. There are two kinds of armsused to keep the ribs and boltingcloth in positionthe rigid ones e,which are attached to every other rib, and the movable ones g, which areattached to the ribs not supported by the arms e. These arms c arerigidly secured to the shaft a at their inner ends, andv to the ribs attheir outer ones, and have no longitudinal movement whatever, while thearms g merely have their inner ends held in sockets in the shaft and canmove freely back and forth.

In each arm g is cut a small groove, and in this groove is made toengage the outer end of the flat spring t', which exerts a constantpressure on the arm to keep it and the rib attached to it pressedoutward against the boltin g-cloth. Every other rib being heldstationary, while the others are pressed outward, the bolting-cloth isheld constantly stretched, and yet can adapt itself to every change ofthe temperature.

In order to slacken the cloth at any time or to draw the movable ribsinward, as when attaching the cloth, it is only necessary to move therings' u o up over the springs toward the arms, when the arms will beforced inward into the shaft, drawing their ribs in with them. As soonas the rings are moved back from over the springs, the springs at onceforce the ribs outward again, and again stretch the cloth.

As shown in Fig. 2, it is only the alternate arms which have an endwisemovement, and hence the bolt will never be drawn out of shape by theweight ofthe flour in it.

By placing the springst' upon the shaft (t in the center of the bolt thedamp iiour never comes in contact with them, and hence can never impedetheir action, as it would do if the springs were located out upon theribs.

Having thus described my invention, I claim- Y l. In a bolting-reel, thecombination of alternate rigid arms and alternate arms having an endwisemovement with springs for moving the movable arms, which springs arelocated at or near the center of the reel, so as to never come incontact with the hour, substantially as shown.

2. In a bolting-reel, the combination of the shaft a, stationary arms e,movable arms g, springs t', rings n o, and ribs c, the shaft a havingholes in or through it to receive the ends of the arms g, substantiallyas described.

In testimony that I claim the foregoing I have hereunto set my hand andseal this th day of January, 1880.

JOSEPH M. SPRINGER.
